Abstract

The utility model provides a locking device for a cover plate of a battery box of an electric toy. A pin [2] is arranged between the conventional battery box cover [3] which is opened by translation and a battery box body [1] and is perpendicular to the battery box cover; a spring [4] for pushing the pin towards the battery box cover is arranged between the pin and the battery box body; and a withdraw stop edge [3b] is arranged on the battery box cover and stands on one side of the pin towards a battery box cover upper tongue when the battery box cover upper tongue [3c] is plugged into a pressing edge. Compared with the prior art, since the pin is required to be pushed in and the battery box cover is required to be moved at the same time, the action is more complex, and a child cannot open the battery box cover to guarantee the safety of the child. In addition, the battery box cover can be conveniently opened without a special tool by people other than children who can conduct multiple actions in a matching way through both hands.

Description

Electronic toy battery case cover plate locking device

Technical field

The utility model relates to a kind of electronic toy battery case cover plate locking device.

Background technology

The battery case cover plate of electronic toy normally cooperates with the pivot hole that is arranged on the length on pivot and the battery box on the battery case cover plate to be installed, and flanging on a tongue and the battery box limit locking that interlocks is arranged on battery case lid one side relative with pivot in addition.This locking device when needs are opened battery case with battery case lid to pivot one thruster is arranged, make tongue withdraw from flanging and just can.But because this locking device as long as single-handed exercise just can be opened battery case, makes the child with oneself also opening battery case and might battery being swallowed and causes danger.There is the people also to open cover plate and designed and a kind ofly with screw the locking of battery case cover plate and battery box just can be opened the electronic toy battery case cover plate locking device of battery case cover plate to reach back-out screw earlier again for preventing that cover plate from directly shifting out to open or pull open to buckle to climb for this reason.But this device user must be equipped with screwdriver, and screw falls existence inconvenience easily; And simultaneously, because of two actions are that carry out front and back, course of action is uncomplicated in fact, and the child still can open after the use of grasping screwdriver easily.

Summary of the invention

To above-mentioned deficiency, the utility model is exactly will provide a plurality of actions of a kind of needs to cooperate just to open and the satisfying electronic toy battery case cover plate locking device opened by the child avoided.

The electronic toy battery case cover plate locking device that the utility model provides; The battery case lid on one side outwardly directed a pair of concentric pivot in both sides cooperates with pivot hole on the battery box; Said pivot hole is a slotted hole, and its length direction is vertical with pivot and parallel with battery case lid; On battery case lid one side relative with pivot, a tongue is arranged, on the battery box limit, flanging is arranged, tongue is filled in flanging following time on battery case lid, and pivot is at an end of long pivot hole, and when tongue withdrawed from flanging on the battery case lid, pivot was at the other end of long pivot hole; One pin is arranged on battery box; Pin is vertical with battery case lid; The spring of pin being pushed to battery case lid is arranged between pin and the battery box, have a resistance to move back the limit on the battery case lid, this resistance is moved back the limit and is filled in the side of flanging retaining of following time at pin tongue on battery case lid at tongue on the battery case lid.

The electronic toy battery case cover plate locking device that the utility model provides; There is resistance to move back the limit on the battery case lid and fills in the side of flanging retaining of following time at pin tongue on battery case lid at tongue on the battery case lid; Make that tongue can not be withdrawed from the flanging on the battery box on the battery case lid; Must make and do not move back the limit and offset both pin being pressed into the battery box direction, can make just that tongue withdraws from the flanging on the battery box and opens battery case on the battery case lid with resistance.Compared with prior art, the utility model is owing to need simultaneously pin to be pushed and the mobile battery lid, and the action more complicated makes child's ability not open battery case lid, thereby guaranteed child's safety.In addition, carry out the non-child that a plurality of actions of both hands cooperate for having the ability, do not need specific purpose tool just can open battery case lid easily.

The diameter of said pin is pointed less than the child, thereby needs tiny object, could pin be pushed like key point, nib etc., can not open battery case lid with further assurance child.

The specific embodiment

1, a kind of electronic toy battery case cover plate locking device is like Fig. 1, shown in 2.Battery case has battery box 1 and battery case lid 3; The battery case cover plate on one side outwardly directed a pair of concentric pivot 3a in both sides cooperates with pivot hole 1a on the battery box; Said pivot hole is the ear nest in the cat ear shape that is inside, is slotted hole, and length direction is vertical with pivot and parallel with battery case lid.On battery case lid one side relative, stretch out a tongue 3c, on the battery box limit, flanging is arranged with pivot.Tongue is filled in flanging following time on battery case lid, and pivot is at an end of long pivot hole.When tongue withdrawed from flanging on the battery case lid, pivot was at the other end of long pivot hole.Battery case is stamped has a button loop 3d on one side of tongue, stir the battery case lid translation and open in order to finger.Outside battery box has an end of pivot hole, a pin chamber is arranged, indoorly through spring 4 pin 2 is installed, the axis of spring and pin is vertical with battery case lid.Spring is a spiral cylinder spring, and extension diameter section is arranged on the pin, and extension diameter section one end withstands on that the other end is buckled in the battery box panel on the spring terminal.Have a hole and pin to stretch out the battery case exterior portions in pivot one side on the battery case lid and make matched in clearance, the limit, hole is formed on the battery case lid tongue and fills in flanging retaining of following time and move back limit 3b in the resistance of pin side of tongue on battery case lid.
